Description
This IE HPFP upgrade reliably increases the output of the OE fuel system delivering over 50% more displacement than the factory unit. This is a popular modification for instance for the MK6 Golf R and MK5 GTI as well as many others. This combination offers fueling support for nearly 600hp at 7500rpm required for many ECU tunes and turbo upgrades. Absolute necessity for stage 2 & big turbo FSI cars.
- Supports Stage 2 and big turbo upgrades
- 50% displacement over OE HPFP
- Powers up to 600HP and 7500 RPM
- Constant diameter piston for long life
- Nitrided surface finish for exact tolerances
- Extreme resistance to wear and abrasion
- Ultralight titanium retainer eliminates valve float
- Retains OE spring to greatly reduce cam follower wear
- Leak-free molybdenum disulphide impregnated seal
- Every kit is tested and verified before shipment
- Engineered, designed, and manufactured in the USA
Increased displacement
By increasing the bore of the cylinder, this pump is able to increase the stock HPFP output by 50%. That makes the pump capable of near 600hp at 7500rpm. While the stock pump is capable for approximately300-350hp at 7000rpm, it does not provide nearly that much in the lower rpm range where most quicker-spooling setups see peak power numbers. Therefore your stock pump is overloaded soon at anything over 300hp. This is a great upgrade for those looking to do a big turbo setup, or even max out the factory turbo at higher boost levels. Our pump will be perfectly calibrated with any ECU calibration tuned for a 9.8MM diameter HPFP piston, which is more or less a standard.
Consistent diameter piston
While many other upgrade kits on the market use a piston that steps down to a smaller diameter, IE have done it better. The tapered piston is usually done to use the original seal and nut assembly. However, doing this means that less than 1/2 of the cylinder is simply guiding the pin at the top of the stroke. This greatly increases wear, leakage past the pin, and decreases the stability of the pin riding in the cylinder. Additionally, using a stepped cylinder causes a pumping action on the bottom side of the piston, which pulses fluid against the shaft seal, increasing the possibility for leakage into the cam follower region. With IEs consistent diameter piston, as with factory design, there is no displacement change occurring on the bottom side of the piston, so there are no pressure pulses against the shaft seal.
Nitrided piston and cylinder
From the factory, the OEM HPFP comes with a nitrided piston and cylinder. This is done to harden the parts significantly, reducing wear and keeping them within wear tolerances. Nitriding is not a coating, but rather a process in which Nitrogen atoms are infused into the atomic structure of the outer surface of the component. This increases its surface hardness and wear properties drastically. IE HPFP is built using the same strategy, as it has proven to be reliable for thousands of miles and cannot chip or flake off like coated components. The thickness and composition of this Nitride layer are independently verified in a materials testing lab for each production batch.
Proprietary alloy
The material that the components are made from is very critical, which is why IE chose to use a proprietary tool steel alloy for the piston and pin. The material used was specifically chosen for its extreme resistance to wear and abrasion. These are critical factors in a system with marginal lubrication provided only by gasoline.
Spring and retainer
In place of the factory steel spring retainer, the IE HPFP uses an ultra-lightweight titanium retainer. Just like a valve spring and retainer, less weight is better, as it reduces the chance of valve float happening. Our retainer was carefully FEA optimized and features a deep weight reduction groove on the outer surface. We also maintain the factory spring, as we have tested them to over 8000 rpm with zero valve float. Other pumps available use an unnecessarily stiffer spring, which puts more pressure on the follower and causes an unnecessary increase in cam follower wear.
Custom seal
The IE HPFP uses a molybdenum disulphide impregnated seal, which increases the stiffness and reduces friction on the seal. Along with this, our custom seals are spring energized to keep them sealing throughout their life with no concern of wearing and leaking. Many of the other HPFP kits on the market reuse the factory seal, which can easily be damaged when the internals are installed. That often causes fuel to leak past the seal and into the crankcase.
Tested before shipping
Each one of the HPFP kits is tested on a fuel pump dyno before shipping. This is done to break-in all components and as a final quality control step. Manufacturers custom-built dyno is fitted with a motor to drive the pump exactly as if it were installed on a running FSI engine! With special electronics onboard, they are able to monitor fuel pressure and rpm, which allows us to collect data and prepare the pumps for install.
Proudly made in the USA
These pumps are manufactured in Salt Lake City.
Compatibility
This fuel pump will fit all belt-drive 2.0T FSI engines, which are found in MK5 GTI/Jetta, MK6 Golf R, B6 Passat 2.0T, 8P A3/S3, B7 A4, and MKII TT. The engine codes for these are (but not limited to): AXX, BGB, BPG, BPJ, BPY, BUL, BWA, BWE, BWT, BYK, BHZ, BYD, BZC, CDLA, CDLB, CDLC, CDLF, CDLG, CDMA, and CRZA. These will also fit the VW and Audi 3.6L VR6 FSI engines, 2007-2009 Mazdaspeed 3 DISI engines, and 2006-2007 Mazdaspeed 6 DISI engines.
For Audi 4.2L FSI engines, two pumps are required.
Can I install this pump without any other modifications?
Pump is a direct fit, but to benefit from it optimally it is recommended to have a matching tune to utilize the IE HPFP. Many of the tunes available are for the 9.8MM piston diameter, and this HPFP can be used with any of those.
Is there a special break-in procedure required once I install the IE HPFP?
No! manufacturer does a break-in for each and every pump on their custom fuel pump dyno, which makes for less work for the end user.
